The RPI2 can power (some) external drives just fine. You can add
max_usb_current=1to the config and it bumps port voltage up. I used a hub (pictured in the center) because I also have bluetooth and wifi dongles running on it. They draw a fair amount of power on their own.
If I just had the drive hooked up, the PI can power it with no problem.disrespectParticipant01/07/2016 at 16:31Post count: 16disrespectParticipant01/03/2016 at 20:01Post count: 16disrespectParticipant01/03/2016 at 15:46Post count: 16disrespectParticipant01/03/2016 at 03:31Post count: 16
I think it may be working now:
*deleted altered entries in /etc/fstab
*formatted 500gb drive to ext4
*ftp’d an iso over to it as a test (took a horrible long time at around 250k/s)
*altered path for PSX to /media/usb0/psx , ISO is found and working
Is there a way to tell by command what capacity there is available on the drive? or through emulationstation? I can see the SD card capacity through ‘sudo blkid’ but that doesn’t list the external drive space.disrespectParticipant01/02/2016 at 21:58Post count: 16disrespectParticipant01/02/2016 at 19:38Post count: 16disrespectParticipant01/02/2016 at 04:57Post count: 16disrespectParticipant01/01/2016 at 23:34Post count: 16
2.5 is more than enough to power the PI at overclock. If you add in peripherals, it’s still enough to power most external (usb powered) hard drives, with a port adjustment in the config.
If you are just worried about controllers and things, you have more than enough power there. My setup is 2amp, and it powers PI at overclock, two controllers, a keyboard, a usb wifi stick, and an external hard disk.disrespectParticipant01/01/2016 at 21:03Post count: 16
I’m currently using the original power switch from the PS1 shell I built into a PI2. I have it interrupting +5 to kill power to the board and a secondary power LED.
If I send term signal through retropie, and shutdown everything so that it’s in an ‘off’ state but still powered, how is this any worse than a mausberry killing the power? (Honest question) I have been using it like this for about a week now.
